Application filed October 2, 1915, Serial No. 53,857. Renewed December 29, 1917. Serial No. 209,805.

To all whom it may concern:

Be it known that I, LEWIS S. Plrn nrrs, a citizen of the United States, res1d1ng at Geneva, in the county of Ontari and State of New York, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

The object of this invention 1s to prov de a new and improved type of stove 1n whlch the oven may be heated either by coal or by gas or by both.

This and other objects of the inventlon will be fully illustrated in the drawings, described in the specification and pomted out in the claims at the end thereof.

In the drawings,

Figure 1 is a perspective view of the stove partly broken away showmg the oven and the arrangements for the heatmg thereof.

Fig. 2 is a vertical section taken on the line 2 x of Fig. 1, showing the left hand side of the oven.

Fig. 3 is a horizontal section taken on the line 3"-3" of Fig. 2. 25

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral 1 Indicates a stove in which is provided a grate 2 in which coal is burned in the ordinary manner for heating the top of the stove and the oven. 3 indicates the top of the stove and 4 indicates the oven. The roducts of combustion from the grate pass t rough the horizontal flue5 at the top of the oven, a

downward inclined flue 6 at the corner of v the oven and a vertical flue 7 at the slde of.

the oven and through a horizontal flue 8 at the bottom of the oven. From the horizontal flue 8 the products of combustion pass rearwardly into the smoke pipe 9. This part of the stove is similar to that which is ordinarily used in coal ranges.

Below the lower left hand corner of the oven is placed a chamber 10 having the gas burners 11 and 12 therein. This chamber is separated from the ash pit and grate or fire box by-a wall 13. At the left of the oven is carried a plate-14 between which plate 14 and the wall 13 is formed the passage way 16 through which the products of combustion from the gas burners 11 and 12 pass upwardly. At the front end of the plate 14 are formed the openings 15, 15, 15, through which a part of the products of combustion may pass around the side of the plate 14 into the oven 4.

As will be seen from Fig. 3, the sides of the plate 14 are curved to make contact with Patented Dec. 24, 1918.

the-wall 13. The plate 14 terminates short 7 of the top of the oven 17 so as to provide an o ening at'the top of the oven throu h w ich the products of combustion from t e gas burners can enter the oven. The plate 14 is fastened to the wall 13 by the bolts. 18. As shown in Fig. 1 the plate 14 and Wall 13 are inclined to the left at the lower corner of the oven where they communicate with and form the chamber that contains the gas burners.

Through the opposite side of the oven at the bottom is provided an opening 19 into the flue 7 through which the products of combustion from the burners emerge into the flue 7. A damper 20 is provided by which this opening may be closed when gas is not beingused' and when the coal is being burned in the grate.

The front of the stove is closed by a plate 21 which carries the door of the oven. This plate is partly broken away so that the structure of the oven may the more clearly appear. This plate also closes the end of the chamber containing the gas burners and the ends of the flues 5, 6, 7 and 8 and the inner .margin of it substantially coincides with the edge of the walls of the oven, coinciding 'with the edge of the straight upper portion of the wall 13.

As will be seen from Fig. 1, four plates on the top of the stove are ordinarily heated from the grate, while four other plates are heated from gas burners which fed with gas through the pipe 23' through suitable valve connections.

The plate 14 is placed at the side or on of the oven andis so constructed and placed that it will not interfere with the heating of the oven by the grate directly through the wall adjacent to thegrate. For this purpose the plate 14 is provided with holes at the side which permit the circulation of air around the end of the plate and the plate stops short of the top of the-oven so that air can pass over the top of the plate. When the ovenis heated by coal along the heat of the side wall of the fire box will be communicated directly to the oven because 'ofthis circulation of air. Because of this flames from the gas burner entering theovenproper and prevents the products of combustion of the burning gas from directly entering the oven at the bottom but allows the hot atmosphere to pass it at points that first from within and from above.

are beyond the reach ofthe flames. This plate distributes the products of combustion from the. gas burner so that they will not only heat the plate but will also enter the oven some distance above the bottom either around the end of the plate or over the top ofit heating the oven more especially from above and after the products of combustion from the gas pass the'plate 14 they must traverse the whole lengthof the oven before they can reach the exhaust openin 19, which exhaust opening is proportioned in size to the opening through which the products of combustion enter the oven from the as burners and pass into the vertical flue? and from thence into the bottom flue 8.. This arrangement of the gas burner and deflecting plate leaves the bottom of the oven free from any obstruction due to the gas burner. It also causes the ovento be heated thereafter when the products of combustion from either coal or gas pass through the flue 8 they are applied to the heating of the oven on the outside so that the oven is also heated from belowldirectly through the one bottom plate of the oven. In this way a good distribution of heat with a uniform heating of the oven is secured which will avoid an intense local heat or overheating in any place.

The heat is applied from a burner outside of the oven first directly to the interior of the oven and thereafter directly through the bottom of the oven and does not have to pass through some other plate forming a second bottom of the oven as well, which plate is' Andused in many stoves where the burner is plate must usually. be removed when the oven 1s heated by the burning of coal alone.

.It will .also be seen that in 'a' plicants' stove the products of combustion rom coal and gas follow substantially parallel courses through the stove and are kept separate from each other by the walls of the oven till they reach the damper 20 and thereafter they mix and follow one and the same course through the stove namely the flues 7 8 and Q'toheat theoven bottom from beneath.

In applicants stove the only change that must be made to adapt it to the several kinds of heating is the openingand closing of the damper 20.
